The current study examined vocalizations that occurred during training of the Picture Exchange Communication System for three U.S. preschool-age participants with autism spectrum disorder. In Phase IV, the protocol incorporates a delay to reinforcement in an effort to encourage vocalizations; however, the manual does not suggest additional…

As 30% of individuals with autism spectrum disorder (ASD) demonstrate difficulties with vocal output, augmentative and alternative communication (AAC) intervention can provide a means for those persons to have the ability to communicate with others. To determine the most effective mode of AAC for individuals with ASD, practitioners must have…

Purpose: Thirty percent of children diagnosed with autism spectrum disorder (ASD) do not develop spoken language. To provide a means of communication for this subset of the population, augmentative and alternative communication (AAC) systems are often utilized. Low-tech options have traditionally been delivered through the in-person modality.…

Purpose: Today, an ever-increasing number of technological advancements are becoming mainstream. As the availability of technological innovations increases, so do opportunities for evaluating any benefits of those innovations in augmentative and alternative communication (AAC) research for individuals with developmental disabilities. One…

According to the American Academy of Pediatrics (AAP), 1 in 59 children are diagnosed with Autism Spectrum Disorder (ASD) each year. Given the complexity of ASD and how it is manifested in individuals, the execution of proper interventions is difficult. One major area of concern is how individuals with ASD who have limited communication skills are…

Individuals with autism spectrum disorder (ASD) often have communication support needs and many rely on augmentative and alternative communication (AAC) systems to communicate. Previous research suggests that AAC use does not preclude the acquisition of spoken language and, in some cases, may facilitate improvements in spoken communication in…

This review investigated virtual reality and augmented reality (VR/AR) communication interventions for children, adolescents, and adults with communication disability and neurodevelopmental disorders, as well the feasibility of these technologies. A search of five scientific databases yielded 5385 potentially relevant records of which 69 met…

This research explored the transformative potential of technology in special education, informed by the researcher's extensive experience in the Los Angeles Unified School District. Highlighting the case of a nonspeaking student with autism who made significant academic progress using an augmented alternate communication (AAC), device, the study…

Between 30 and 50% of individuals with Autism Spectrum Disorder (ASD) do not develop vocal language deemed functionally acceptable to meet their daily communication needs. As a result, individuals with ASD may require intervention alternatives to vocal speech, such as augmentative and alternative communication (AAC). However, very little is known…

Enabling functional communication is critical for accessibility in school and society for all pupils. This systematic review analyzed the results of educational studies on developing communication skills for learners ([less than or equal to]21 years) with autism spectrum disorder and comorbid intellectual disability. Systematic database searches…

This meta-analysis aimed to evaluate single-case studies that used high-tech speech-generating devices (SGDs) for children with autism spectrum disorders (ASD) ages 0-8. The focus of this review was to measure the effect size of high-tech SGD intervention on verbal behavior. The review included 20 studies with 54 participants with ASD. The results…

The purpose of this study was to evaluate the use of an interrupted chain procedure and a time delay with full physical prompts, in the establishment of peer manding, within a naturally occurring classroom routine. The participants included three preschool aged children with autism spectrum disorder (ASD), who used a tablet-based speech-generating…

This community-partnered participatory study explores the outcomes of adult alternative and augmentative communication (AAC) users who qualified for special education under autism and/or intellectual disability. This multiple case study examines outcomes, the transition to adulthood, K-12 and special education experience, and the diagnosis and AAC…

A systematic review was conducted to analyze the scope and breadth of the existing training protocols for establishing social and communicative behavior using high-tech, touchscreen devices. This review aimed to determine the degree to which studies evaluating high-tech communication aides have established procedures to extend, or completely…
